Danny Cowley’s side extended their unbeaten league run to eight games following a goalless draw against their promotion rivals.
The south-coast side edged the game, creating the better chances but were denied by keeper Bailey Peacock-Farrell.
Massimo Luongo was shown a straight red card in the 68th minute but the Blues couldn't beat the valiant 10 men.
There was a mixed opinion at the full-time whistle as some fans questioned Pompey’s inability to break the visitors down but most were resigned to the fact that it was a positive result despite failing to break the deadlock.
Here’s what Blues fans had to say about the game on nTwitter.
@EllisMartin: Disappointed not to get the win after the red card
@PORTSMOUTHFCLEE: For a 0-0 I really enjoyed that game. Two good sides Pompey and Sheffield Wednesday, no complaints with that. We will both be in the mix come the end of the season.
@CapiTweets: Fair play to Wednesday, real gritty performance.
Think we would get 3 points there if we had sufficient squad depth. Cowley bros deserve to be back financially in January.
CE_1999: Would have taken a point before the game, but we really should have won that.
@Will_Mason7: Feels like a loss gotta be beating teams like that. All over them 2nd half. No end product again. Results like this will bite us in the a*** at the end of the season.
@Dan_scoutcast: It’s a ‘decent’ point on paper, but in reality we should have won that quite comfortably.
Just lacking the clinical decisions in the final third.
@Real_Dan_Horton: Harness was very disappointing tonight, Azeez absent again. Need Morrell back asap.
@Steve_Wrixon: A lot of huff and puff but lacked any real threat. Set pieces woeful. Red card changed the game but Wednesday came out strong.
Point probably deserved in the end.
@Pearcy3000: All I want for Christmas is……. 2 strikers.
@george_lashley: How does Williams get game time week in week out?
